Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.

As usual, Hampus is out cycling. He is driving at 30.0 km/ h when he comes to a small hill that is 11 m high and 350 m long. Hampus and the bike weigh 95 kg together. a) What kinetic energy does Hampus have just before the hill? b) How much extra energy must Hampus produce to maintain a constant speed (30.0 km/ h) throughout the hill? c) How long does it take him to drive up the hill? d) What effect must he develop on the hill? Once at the top of the hill, the ground is flat. Hampus is tired and stops pedaling. After 12s the cycle stops. e) How big is the coefficient of friction? You can assume that is constant throughout the deceleration and that it includes both drag and rolling resistance.

Which of the following statements are true? Select all correct. Question 3 options: If an object speeds up, then the total work done on the object was positive. If an object moves at a constant speed, then the work done by each individual force is zero A force must be parallel to the displacement to do any work. If a force is perpendicular to displacement, it does zero work. If a force has a component in the opposite direction of the displacement, it does positive work. If an object doesn't move, then the work done by every individual force must be zero.
